Standard and OEM accessories

GeneralEaton offers a variety of accessories to increase the reliability and availability of power capacitor installations with its Cooper Power™ series products. Opti-G™ fuse flippers come as standard equipment on substation bank assemblies and a line of Nature Guard™ wildlife protectors may be specified when required by special system needs. Also, these accessories can be supplied as OEM devices, allowing them to be specified as original equipment on assemblies not built by Eaton.

Opti-G fuse flippersYears of research have gone into the development of Opti-G (Optimal Geometry) fuse flippers. Analysis of the flipper’s motion and functional requirements has allowed for the optimization of their geometry and mechanical characteristics. The resulting design provides superior orchestration with the remainder of the expulsion fusing system. Benefits of the Opti-G flippers include:• Elimination of leader whipping:

This phenomena is manifested by the operation of multiple fuses when only one fuse was required to operate. Ranging from a nuisance to a major operating concern, leader whipping can cause banks to trip off line without the benefit of alarm relay operation.

In some cases, leader whipping has been responsible for sympathetic capacitor unit failures, tank ruptures, arcing between buswork, and high overvoltage generation.

• Improved low-current clearing: The positive ejection of the operated fuse link allows rapid dielectric strength buildup within the fuse tube, ensuring proper clearing even under low-current/low-energy conditions.

• Elimination of Permanent Deformation: Some conventional flipper spring designs, after having been left in a cocked position for many years, may permanently take up this shape and lose their flipper action. This can result in disastrous fuse restriking and improper clearing of faulted capacitor units.

Opti-G flippers are available in a number of styles for various mounting configurations. Supplied as standard equipment with Eaton’s substation banks, these advanced technology flippers are ideal for PCB replacement/retrofit applications. See Table 1 for available ratings and Figure 1 for mounting tolerances.

Nature Guard wildlife protectorsItems in the Nature Guard line of wildlife protectors are designed to give your equipment the ultimate in protection against nuisance outages caused by aggressive or pesky members of the animal kingdom.

Nature Guard terminal covers

These heavy-duty terminal covers (Figures 2A and 28) are ideal for pole-mounted racks where squirrels or other aggressive animals have proven conventional terminal covers inadequate. They offer:• Screw-on assembly: Cannot be pried off• Skirt hugging design: Edges cannot be lifted off of the top

bushing skirt. This prevents foreign matter from being deposited under the covers.

• Bacterial resistant: Bacterial growth, which turns conventional covers black over time, is eliminated

• UV resistant: Minimal degradation from prolonged exposure to ultraviolet (UV) radiation is assured

• Heavy-duty: The heavy-duty design and 15 kV withstand capabil-ity of the covers ensures long life

Also available is a line of light-duty birdguard terminal caps (Figure 3). These are standard equipment on all Eaton pole racks and are ideal for installations with limited animal problems. Nature Guard terminal covers are available for a variety of equipment used in pole-mounted capacitor rack applications. See Table 2 for application information.

Nature Guard expulsion fuse plug

Expulsion fuse plugs fit snugly in the end of expulsion fuse tubes, preventing insects from nesting in the body of the tube. Some insects, such as mud dauber wasps, attach to the cavities provided by fuse tubes. Their dense mud nests can soon clog the expulsion tube, preventing the fuse leader from being ejected properly during fuse operation. The fuse plug prevents this nesting activity while allowing the fuse leader to pass out of the tube. Nature Guard fuse plugs have been specially designed not to interfere with proper fuse leader ejection. Refer to Table 3 for more information.

Capacitor hanger framesEaton manufactures capacitor hangers for three or six capacitors. These hangers, made of galvanized steel, are shipped unassembled to allow for a smaller and more compact package. Note that these hangers are not recommended if switches are to be used with the capacitors. See Table 4 for ordering information and see Catalog Data CA230001EN Capacitors - Pole-Mounted Racks with Single-Phase Units for rack frames suitable for direct mounting of switches or other accessories.

Capacitor unit mounting spacersThese corrosion resistant aluminum spacers bolt on to the bottom of the capacitor unit hanger bracket, effectively increasing the “D” dimension shown in Catalog Data CA230003EN Medium-Voltage, Standard-Duty, Heavy-Duty, and Extreme-Duty Single-Phase, Unfused Capacitor Units and Accessories. Spacers are available from 2” to 6” (50.8 mm to 152.4 mm) in 1” (25.4 mm) increments. Spacers should be used whenever an installation requires a larger “D” dimension. This most commonly occurs when replacing old capacitors in individually fused substation banks with capacitor units having differing “D” dimensions. Maintaining this dimension is usually required to ensure proper fuse operation. See Table 5 for ordering information.

Inrush current-limiting reactorsInrush current-limiting reactors limit transient discharge currents during switching of parallel steps in closely spaced capacitor banks. The fully tested design assures proper protection for switching equipment. Inductance selected will limit inrush current to safe levels in most banks. The compact design of the CCM13B1 reactor (Figure 7) is particularly suited for use in pole-mounted and metal-enclosed banks.
